Abstract

A broadband wireless access communication system including a serving BS which broadcasts a MOB_NBR-ADV message to an MS is provided. A method for configuring the MOB_NBR-ADV message is also provided, and includes adding a specific field, which represents whether at least one information field constituting the MOB_NBR-ADV message exists, to the MOB_NBR-ADV message, determining if at least one information field is included in the MOB_NBR-ADV message, and determining a bit value of the specific field according to whether at least one information field is included in the MOB_NBR-ADV message.

Claims

1. A method for configuring a MOB_NBR-ADV message in a broadband wireless access communication system including a serving BS which broadcasts neighbor BS information to an MS, the method comprising:

adding a specific field, which represents whether at least one information field constituting the MOB_NBR-ADV message exists, to the MOB_NBR-ADV message;

determining if at least one information field is included in the MOB_NBR-ADV message; and

determining a bit value of the specific field according to whether at least one information field is included in the MOB_NBR-ADV message.

2. The method as claimed in claim 1, wherein the bit value of the specific field can be set to ‘

0’

or ‘

1’

for information fields included in the MOB_NBR-ADV message from among a plurality of the information fields.

3. The method as claimed in claim 1, wherein the bit value of the specific field can be set to ‘

0’

or ‘

1’

for information fields not included the MOB_NBR-ADV message from among a plurality of the information fields.

4. The method as claimed in claim 1, further comprising configuring the MOB_NBR-ADV message with information fields which are determined to be included in the MOB_NBR-ADV message according to the determination on whether to include a plurality of information fields.

5. The method as claimed in claim 1, wherein the information field is Operator ID field, which represents an inherent identifier of a base station.

6. The method as claimed in claim 1, wherein the information field is neighbor BS identifier (Neighbor BS-ID) field.

7. The method as claimed in claim 1, wherein the information field is handover process optimization (HO Process Optimization) field, which represents information about indispensable procedures and information about omissible procedures during handover to a neighbor BS.

8. The method as claimed in claim 1, wherein the information field is related to quality of service (QoS) fields, which represents QoS classes supportable by a neighbor BS.

9. A system for configuring a MOB_NBR-ADV message in a broadband wireless access communication system including a serving BS which broadcasts neighbor BS information to an MS, the system comprising:

a serving BS for adding a specific field, which represents whether at least one information field constituting the MOB_NBR-ADV message exists, to the MOB_NBR-ADV message, determining if at least one information field is included in the MOB_NBR-ADV message, and determining a bit value of the specific field according to whether at least one information field is included in the MOB_NBR-ADV message.

10. The system as claimed in claim 9, wherein bit value of the specific field can be set to ‘

0’

or ‘

1’

for information fields included in the MOB_NBR-ADV message from among a plurality of the information fields.

11. The system as claimed in claim 9, wherein the bit value of the specific field can be set to ‘

0’

or ‘

1’

for information fields not included the MOB_NBR-ADV message from among a plurality of the information fields.

12. The system as claimed in claim 9, wherein the serving BS configures the MOB_NBR-ADV message with information fields which are determined to be included in the MOB_NBR-ADV message according to the decision on the determination of a plurality of information fields, and transmits the MOB_NBR-ADV message to the MS.

13. A method for generating a neighbor advertisement (MOB_NBR-ADV) message in a broadband wireless access communication system including a serving base station which broadcasts neighbor base station information to a mobile station, the method comprising:

determining if at least one information field is included in the MOB_NBR-ADV message;

adding a NBR-FLAG field, which is at least one bit represents whether one information field constituting the MOB_NBR-ADV message is omitted or not, to the MOB_NBR-ADV message; and

determining a bit value of the NBR-FLAG field according to determining whether the information field is included or not in the MOB_NBR-ADV message.

14. The method as claimed in claim 13, wherein the information field includes one of a Operator ID field, a Neighbor BS-ID field, a handover process optimization (HO Process Optimization) field and a QoS related field.
